Waifu2x is an AI tool for improving image quality, designed primarily for anime-style artwork.
The original Waifu2x was created by the user nagadomi and published as open source on GitHub. You can clone the repository, run it on your PC, or integrate it into your own projects (including websites and apps).
Waifu2x uses Lua and Torch7, and may require CUDA for faster GPU processing. Setup typically involves cloning the repo, installing dependencies, and running a command with parameters for input/output and processing mode (noise, scale, or noise_scale).
Because local installation can be complex, enthusiasts have built third-party web interfaces where you upload an image, choose settings, and process it online. Examples mentioned include:
These sites are not affiliated with the original project and generally rely on the open-source GitHub version.
